T 0 all whom it may concern:

Be it known that I, SAMUEL F. GREENE, a

citizen of the United States, and residentlof Irvington, in the county of EsseX'and State of New Jersey, have inventedcert'ain new and useful Improvements in Molds for Type-Casting Machines, of 7 which the following is a specification.

In the art of printing it is necessary that means be supplied for filling 'up the blank spaces in the forms between and around theprinted matter or i illustrations. F on; this purpose, the printer uses blocli'sof metal of various sizes and'shapes which are khownns slugs, quads, leaden rules and quotat ons according to their particular size-and sh'ape.

Some of these, namely the slugs, leaden rules and quads may be and generally arecast' on type casting machines, but the quotations:

being the largest filling members, are made intype foundries; When made-of iron they the type casting machines instead of having to obtain them from outside sources, from which the supply may not always be'available. Another advantage is that-the printer is then able to east quotations inthesizes most needed, vorcast them in special sizes as requirements demand. Heretofore it has been impossible to'cast quotations ontypesizes. 7

. vide a mold for this purpose as aiseparate articleiof manufacture adapted to be at-- tached to a type-casting'machinewithoutjal tering the construction thereof except in minor deta'ilsnot afie'ctingfits efliciency'or limiting its uses.- Another object of thefin- Type casting machines as arranged at Present cannot cast types larger than thirty-j six points, and leaden 'rules, slugs or quads 1 up to twelve points'onlyi' It 'is "one of the; objects of this invention to 'providea mold adapted. to cast quotations in sizes from thirty-six points and up to seventy-two points square. I

Another object ofthe invention is to provention is to provide a mold for casting quotations which may be used in combina tron with a type casting maehine and some of its attachments provided for casting} leaden rules form-stance.

Accordingly, my invention is embodied in a mold-constructed and arranged asherei'n after set forth and illustrated in the accom:

R r n t ss- 4 and my"im*--- proved mold is'preferably made of steel a d 1 comprises a'base :10which forms the bot tom'portion 11 of the mold proper which is base 'supportsthe several parts of the mold.

The mold 12 is squareand is formed of four elements. one of these is *the'fi'xed base portion 13, Fig; 45, which forms the one mold side "onwall 14. :The opposite wall 15*is formed bythe element or mold wall piece 16, which is laterally" adjustable against "am adjustable stop2 l by means of the slots "17 .f

"In closing the mold" the' edge '20 ofthe abutmententers a notch 21 in themold Walt 1% The fourth-mold wall orside is formed the mold blade into it through the mold hole 28 in the bottom and in the same manner in which the metal is pumped into the ordinary type mold. When the quotation has been cast, the mold is. opened by elevating the centering pin and moving the mold blade abut ment 19 to one'side, to the left in Fig. 1.

Thereafter, the mold blade moves forward or to the right, into and through the mold and pushes the cast quotations out of the mold .and in front of the type pusher 30.

As the quotation leaves the mold it is moved I over a small lug 31 and thereby tipped so as to free it completely from the mold blade head 22 and the mold,- for which purpose the said head is also provided with a central projection 32, see Figs. 2 and5. 13y these means a clean break between the cast quotation and the mold is obtained.

ment which slides on the mold base .10 betweenthe mold portion 13 and a fixed guide member 34. 'Overhanging guide strips 35, 35 keep the type pusher inposition. When thecast quotation has been moved in front of the type pusher, the latter is moved to the left, in Fig. 1, and pushes the finished quotation to one side of the mold and for- Ward on the base 10. face 36 of the type pusher is inclined so as to move the quotation away from the mold in anoblique direction as is obvious. While the type pusher is removing the quotation,-the abut-c 'ment 19 is again moved to close the mold, the mold blade is moved to the left to un-.

cover 7 the hole 28, the centering pin descends to close the mold and another quotation is cast. y

In order to operate the mold as aforesaid,-

casting machine very quickly and without requiring the use of any special tools. The mold and its several parts are positioned on the type-casting machine and attached thereto in the following manner, the typecasting mold having first been removed.

The typecasting machine is represented in Figs. 2 and 3, by a portion of its framework 40. 41 is the galley pan bracket. In this instance the latter supports a pan or tray 42 which receives the cast quotations as they come from the mold and are pushed to one side by the type pusher. 43 is a bolt which passes through a portion of the frame 40 and bears against the mold base 10 to secure the same in position. 1 may use other bolts, notv shown, which are arranged according to the shape of the type-casting machine.

'The numeral 45 denotes the center pin operating lever of the machine. 46 is a bracket secured to said lever when the leaden rule mold of the machine is used. In the said bracket, which herein is treated as a part of the center'pin operating lever, I drill two holes for the bolts 47, 47 with which I attach a bracket 48 to the lever. To thebracket 48 is secured in turn the center pin 26 as shown in Figs. 8 and 4. Fig. 1 does not show the center pin operating leverrand the center pin.

The particular construction of the center pin is as follows: At the lower end the pin is provided with a ball and socket joint composed of the ball 49 and the socket member 50, which is held onto the ball by the square split collar 51. The socket member has a tongue 52which enters a recess 53 in the ball to prevent relative turning of these two The type pusher 30 is a reciprocating ele f partsflThe center pin head or male mold member 25 is detachably carried by the socket member 50 by a tongue and groove connection 54 and is provided with a flange 55 adapted to rest upon the mold. The center pin extends up through an upper guide link 56 which is secured to the bracket 48 by a wing bolt 57. A spring 58 is interposed between the center pin and the link 56. '59 is, a lower guide link secured to the mold at 60, see Figs. 2 and 3, and which link is pivoted at 61 to a sleeve 62 surrounding the center pin. It will therefore be seen, that the center pin may be accurately adjusted in position over the mold by swinging the upper and lower links 56 and 59 on their pivots at 57 and-60respectively The mold itself is placed so that the mold hole 28 comes within a cutout portion 64 in the frame of themachine, into which cut out portion ,the ,nozzle 65 projecting upward from the melting pot.,66v ismoved, and so that when the nozzle is raised it fits into the said.hole 28. j

Thetype pusher 30 is operated from anarm 67, pivoted to the mold base at 68, by means of the screw-69 and slot 70 insaid arm. 7 The free end of the arm is connected at I71 to the type pusher. operating lever 72, showninFig. 8, which in turn is connected tothetype pusher bell crank on the machine 6 which is well known to those skilled in the art and therefore not shown. p 1 The mold blade is provided with a hole a the type pusher to remove the finished quo- 73 into which fits a stud 74 onthe. mold blade operating slide '75..Wl110h is alsoapart of the machine. The mold blade is operated against the micrometer stop attachment 76 on -the type-castingmachine. The heads .22 on the mold blade are of different sizes depending uponthesize .of'quotation to be cast and'the head is securedtoi the blade by screws 77. r 78 is aitop guide piece for the mold blade. 23.

The mold blade iabutment 19 'slidesbetween the mold member 16and a guide piece 79 and underneath suitable guide strips80 and 81 which extend from a bearing 82. To the latter is pivoted at 83 a rock arm 84. One end of the rock arm is connected'at 85 to a link 86 pivoted at 87 to the abutment 19. To the other end of,the arm is :pivoteda curved link 88 which in turn is connected to the connection 89 carried by the centering pin operatinglever as apart of the typecasting machine. V

The center pin operating lever oscillates in a vertical plane. centers the male mold member 25 in the mold 12, being guided in its downward movement by the sleeve 62. At the same time the connection 89 depressed the curved link 88, thereby rocking or oscillating the rock arm 84, raising the pivot 85 and through the link 86 moving the mold blade abutment 19 to close the mold. Both the male mold member and the link 88 are depressed under spring pressure as is obvious from the drawing. Also at this time, the mold blade operating slide 75 moves to the left in Figs. 2 and 3, thereby uncovering the mold hole 28. The limit of this movement is reached when the end of the mold blade strikes the micrometer stop.

The finished cast quotations are shown in Fig. 9. There may be several sizes because of the adjustability of the mold, which may be made wider by adjusting the position of the part 16, and made longer by adjusting the micrometer stop 76. During the casting, the type pusher operating lever actuates tation.

Preferably the mold is cooled by passing.

water from the water connection 92 on the machine through water channels 93 in the mold piece 13, see Fig. 2.

From the foregoing it will be seen that I have provided a mold for casting quotations on a type casting machine, adapted to be attached to the latter and operated in combination therewith. Besides the mold as shown in Fig. 1, the invention comprises the When it descends it at the one end thereof, a mold blade, a. centeringpin, a1 centering pin head carried by said .centermgpin: and adapted toextend into:the said mold and close thesame, means for. operatingsaid mold blade to eject-the castaquotation: from the moldandmeans for operatingzthe said centering pin.
